How to Fix / Troubleshooting
Safety: Unplug the cooler before accessing interior panels.
- Check airflow: With the unit running (briefly), feel for air movement at the lower zone vents. Then unplug.
- Inspect lower fan: Remove lower zone back panel and check the evaporator fan motor. Replace if not running or noisy.
- Clear ducts: Ensure no insulation or debris is blocking air passages between zones.

- Check damper: On models with a damper, verify it opens to supply cold air to the lower zone; replace the air damper motor assembly if stuck.
